Some of the guys had been asking: How close is Alaska to Russia? Answer The narrowest distance between mainland Russia and mainland Alaska is approximately 55 miles. However, in the body of water between Alaska and Russia, known as the Bering Strait, there lies two small islands known as Big Diomede and Little Diomede. Interestingly enough, Big Diomede is owned by Russia while Little Diomede is owned by the US. The stretch of water between these two islands is only about 2.5 miles wide and actually freezes over during the winter so you could technically walk from the US to Russia on this seasonal sea ice.

ARRL Volunteer Monitors Recognize Good Operators....how about the bad ones?

ARRL Volunteer Monitors recognized 13 operators in 10 states with Good Operator letters during the second quarter of 2020. Among the operators recognized were CW and SSB operators on 20 and 40 meters, outstanding net operators on 2 meters (including a net control of the Central Indiana SKYWARN Net), and an operator on 40 meters who demonstrated exemplary courtesy and assistance to amateurs with technical issues.

SAQ Alexanderson Day in the Age of COVID-19

Despite mid-summer conditions, at least seven US listeners, most of them radio amateurs, were able to copy the 17.2-kHz signal from the SAQ Alexanderson Alternator at the World Heritage Grimeton Radio Station in Sweden. The July 5 transmission from the vintage electro-mechanical transmitter commemorated the annual Alexanderson Day. All told, more than 600 reception reports were received — a new record.

“The odds were not optimal this year, with the ongoing coronavirus pandemic, and in the early Sunday morning, the rain was pouring down, and heavy wind gusts made it hard to even take a peek at the antennas outdoors,” the report from SAQ said. “The transmitter hall was empty except for five members of the Alexander Association.”

Dating from the 1920s, the Alexanderson alternator — essentially an ac alternator run at extremely high speed — can put out 200 kW but typically is operated at less than one-half that power level. Once providing reliable transatlantic communication, it is now a museum piece and only put on the air on special occasions.

The transmitter was developed by Swedish engineer and radio pioneer Ernst Alexanderson, who was employed at General Electric in Schenectady, New York, and was chief engineer at the Radio Corporation of America.

Two Alexanderson Day transmissions were made. “On the first transmission, the rainy weather was making it hard at first to reach good output to the antenna, but after a few minutes with the ‘VVV VVV VVV de SAQ’ loop, the system started to dry, and the amps [antenna current] increased. Skies cleared for the second transmission later in the day, and, according to the report, the antenna current rose to 60 A, which ‘is optimal,’” the report said.

The occasion marked the inaugural transmission by Kai Sundberg, SA6KSU, at the helm of SAQ in a radio uniform dating back to the 1960s.

An article about Alexanderson Day, “The Legacy of Radio at Grimeton Station, SAQ,” appears on page 66 of the July 2019 issue of QST

New 2700km+ IARU Region-1 tropo record on 23cms between Ireland and the Canary Islands

On the 17th of July 2020, there was a tropo opening between the Canary Islands and the UK & Ireland on the VHF & UHF bands.

A remarkable contact was made on 1296 MHz between EA8CXN and EI2FG which turned out to be a new IARU Region-1 tropo record for the 23cms microwave band.

Unlike other recent records, the mode used this time was SSB with 5/1 and 5/4 reports exchanged. The distance was an amazing 2714 kms.

The old record of 2661 kms was set back in July of 2017 between EA8AVI and M0VRL.

Radio Amateur Takes Part in Historic First Commercial Human Spaceflight to ISS

08/05/2020

Bob Behnken, KE5GGX, was one of two NASA astronauts who made spaceflight history over the weekend. Behnken and Doug Hurley were the first astronauts since the 1970s to make a water landing, after their Crew Dragon capsule splashed down in the Gulf of Mexico on Sunday. On May 30, the pair made history as the first live crew to be launched into space in a commercial vehicle, for a stay on the International Space Station (ISS), marking the return of human spaceflight to US soil for the first time in nearly a decade.

A SpaceX Falcon 9 vehicle carried the crew into orbit from Cape Canaveral. The so-called “Demo-2” was the last major test for SpaceX’s human spaceflight system, to be certified by NASA for operational crew missions to and from the ISS. Four huge parachutes carried the Crew Dragon capsule to a safe splashdown near Pensacola, Florida, on Sunday, August 1.

“On behalf of the SpaceX and NASA teams, welcome back to planet Earth,” SpaceX Engineer Michael Heiman radioed to the crew after their landing. “And thanks for flying SpaceX.”

NASA Administrator Jim Bridenstine proclaimed that the US was entering a new era of human spaceflight, noting that NASA was no longer the only option for US space travel. “We are going to be a customer,” he said. NASA has contracted with two companies — SpaceX and Boeing — to ferry astronaut crews to and from the ISS.

While part of the space station crew for 2 months, Behnken and Astronaut Chris Cassidy, KF5KDR, the sole American on board when their Endeavour capsule docked, carried out four spacewalks to install new batteries on the ISS.

The SpaceX Crew Dragon vehicle was designed for short-term missions, and Behnken and Hurley’s mission had only been expected to last a week. As a result, Behnken did not receive Amateur Radio on the International Space Station (ARISS) training on the radio gear in the Russian sector. NASA subsequently decided to monitor the mission and make a decision on how long the Crew Dragon would stay. Cassidy fielded all ARISS school contacts.

New England Division Convention Canceled Due to COVID-19

08/05/2020

Initially scheduled for July, the Northeast HamXposition, host of the 2020 ARRL New England Division Convention, was moved back to November because of the coronavirus pandemic. Now, the in-person event is off until next summer, although some activities will take place online this year. Renamed before the 2019 show, the Northeast HamXposition has succeeded the long-running annual Boxboro hamfest in Boxborough, Massachusetts. As announced early this year, the next HamXposition will take place in a new location — Marlborough, Massachusetts.

“Large indoor gatherings such as our convention are currently prohibited by Massachusetts state law,” Northeast HamXposition Chair Bob DeMattia, K1IW, said over the weekend. “This is highly unlikely to change by November. Unfortunately, we will not be able to hold a physical convention this year.”

Still on will be the W1A special event station, which will be on the air over the weekend of October 1 – November 1. “W1A will be operated from the operators’ home stations, DeMattia explained. “We will also be hosting a Saturday evening virtual banquet on November 7, featuring a guest speaker. Order your favorite take-out or delivery, pull up a chair to your screen, and join your friends for an interesting presentation. After the talk, virtual break-out rooms will be available for you to converse with your ‘table.’”

The Nashua Area Radio Society will be running an online version of its “Ham Boot Camp.” This is a multi-session program for hams young and old to learn about the various amateur radio activities.

Eastern Massachusetts Amateur Radio Emergency Service® (ARES®) will conduct online versions of their training sessions.

“We look forward to seeing everyone in person at our 2021 convention on July 23, 24, and 25, 2021, DeMattia said.

Like  W1ITT I also took my FCC exam on the 16th floor of the U.S. Customs-house in Boston. The windows were open and the pigeons were perched on the marble window sills. They would occasionaly fly through from one corner window to another. I was seated,  alone,  at a table with a code machine attached to a set of earphones, a pad of yellow paper, and 3 or 4 sharpened pencils. The examiner explained that I would hear 5 minutes of Morse Code, and in order to pass the test I would have to copy 1 minute at 100%.  My best minute was 1 character short of the required minute. During that minute i had copied  " a ship loaded with 20,000 long tons of molybdenum disulfide". I will NEVER forget that phrase as long as i live. The examiner passed me with this explanation " You didn't fall asleep during all those dashes, and there was no way you could copy ahead or guess at Molybdenum Disulphide,  so I'm passing you". I thanked the gentleman and became W1GWU when the coveted FCC license arrived in the mailbox a few unbearably long days later. I AM an old guy and proud to be called a "Know Code Ham". Bob W1GWU

BBC program on pirate radio

In the 1980s a new generation of pirate radio stations exploded on to Britain's FM airwaves. Unlike their seafaring swinging 60s forerunners, these pirates broadcast from London's estates and tower blocks to create a platform for black music in an era when it was shut out by legal radio and ignored by the mainstream music industry.

In the ensuing game of cat and mouse which played out on the rooftops of inner-city London across a whole decade, these rebel DJs used legal loopholes and technical trickery to stay one step ahead of the DTI enforcers who were tasked with bringing them down. And as their popularity grew they spearheaded a cultural movement bringing Britain's first multicultural generation together under the banner of black music and club culture

Smartphone app helps identify unknown data modes

There's an incredible amount of radio signals.

It's impossible to know them all, let alone recognize them. So why not get help from SignalID?

At the moment, it recognizes about twenty signals (the exhaustive list is below) With only 5 seconds of recording time, it tries to recognize the signal.

To use it:
Set the frequency and bandwidth properly.
Selecting the frequency range. (0-30 MHz / Other) Place the microphone of the telephone near the loudspeaker. (The quieter the environment is around, the fewer errors will occur) Press the big button that dances.
Wait 5 seconds. (Time required for record)

Tips :
The algorithm is based on frequency, a wrong tuning of your radio/SDR will result in an erroneous detection.
The recording is limited to 5 seconds, for practical reasons. Recognition of a signal may require several attempts.

If you notice bugs, have remarks or suggestions, please leave a comment.

Here is the non-exhaustive list of recognized signals :

- RTTY (Commercial 85Hz, 170Hz, 450Hz, 850Hz, Amateur 170Hz)

- PactorI (Standard, FSP, FEC, SELCALL)

- ASCII (170Hz)

- ALIS

- Codan8580 (200Hz, 250Hz)

- CIS36_50

Slow-Scan Television Activity August 4 -5 from ISS will Commemorate Apollo-Soyuz

Russian cosmonauts on board the International Space Station plan to transmit slow-scan television (SSTV) images on August 4 – 5. The SSTV images will commemorate the joint Soviet-US Apollo-Soyuz mission, the first international space mission, which took place in mid-July of 1975. The activity will use the RS0ISS call sign, and transmissions will take place on 145.800 MHz, likely using SSTV PD-120 mode. European Space Agency (ESA) Education anticipated the commemorate transmissions in a July tweet.

“We are expecting the ISS to transmit pictures in the next weeks for the 45th anniversary of the Apollo-Soyuz test project. This is a perfect opportunity to try this activity for yourself,” ESA Education said.

A subsequent announcement appeared on the Amateur Radio on the International Space Station (ARISS) blog on July 27.

“The final crew schedule for the week of August 3 – 9 was released recently, and it showed a MAI-75 activity scheduled for August 4 and 5,” the ARISS blog post said. The SSTV activity comes just days after the SpaceX Demo 2 undocking from the ISS. SpaceX Demo 2 marked the first time space station crew members have been launched from US soil since the end of NASA’s space shuttle program.

The schedule calls for setup and day 1 SSTV operation to begin on August 4 at 1225 UTC and continue until 1810 UTC. Day 2 SSTV operation on August 5 will begin at 1115 UTC and continue until 1845 UTC.

While typical MAI-75 SSTV passes are scheduled to occur above Moscow and Russia, and will be visible in the UK and parts of Europe, individuals elsewhere in the world may be able to capture images using their own software via one of the many remotely accessible software-defined radios (SDRs) that cover 2 meters.

ESA has released a video aimed at non-amateurs, “How to get pictures from the International Space Station via Amateur Radio,” along with a collection of tutorial videos explaining how to receive ISS slow-scan television (SSTV) pictures for different computers and mobile devices. See also the article, “Pictures from space via ham radio.” AMSAT-UK offers an ISS SSTV tutorial for beginners. — Thanks to AMSAT News Service, ESA

Hurricane Watch Net Reactivates as Hurricane Warning Posted for the Carolinas

With the National Hurricane Center (NHC) expecting Tropical Storm Isaias to become a hurricane again later today and make landfall this evening, the Hurricane Watch Net (HWN) reactivated at 1600 UTC on 14.325 MHz. HWN Manager Bobby Graves, KB5HAV, said the net will shift operations at 2300 UTC to 7.268 MHz, where it will remain until no longer needed by the NHC. A hurricane warning is in effect from the South Santee River in South Carolina to Surf City, North Carolina.

“The center of Isaias will then approach the coast of northeastern South Carolina and southern North Carolina within the hurricane warning area later today,” the NHC said. The center will then move inland over eastern North Carolina tonight, and move along the coast of the mid-Atlantic states on Tuesday and into the northeastern United States by Tuesday night.”

The HWN initially activated on July 31 at 1500 UTC, when Isaias was about 245 miles southeast of Nassau. “During the next 41 hours, we relayed the latest advisories to those in the Bahamas, south Florida, as well as mariners and shortwave listeners, Graves said. “Because Isaias was forecast to regain strength to a Category 1 hurricane, and hurricane watches and warnings remained in effect for the Florida coast as well as areas in the Bahamas, the Net remained activated.” After the NHC dropped all hurricane watches and warnings on Sunday morning, and the storm was no longer believed to become a hurricane, the HWN secured operations on Sunday, August 1.

“During the course of 41 hours, we never received any reports from the Bahamas,” Graves said. “We did hear from many south Florida stations, but the storm was not yet close enough at the time for [that area] to be adversely affected.

As of 1500 UTC, Isaias is forecast to make landfall tonight as a Category 1 hurricane and is expected to bring strong winds and heavy rainfall from the eastern Carolinas to the mid-Atlantic coast tonight and Tuesday. The storm was some 90 miles east-southeast of Brunswick, Georgia, and some 220 miles southwest of Myrtle Beach, South Carolina. Maximum sustained winds are 70 MPH, just a shade below Category 1 hurricane strength.

“We are slowly moving into the heart of the 2020 Atlantic Basin Hurricane Season, so, please do not drop your guard,” Graves advised. “If you haven’t done so already, now would be a good time to review your Family Emergency Plan and review your Emergency Supply Checklist. We have links to download both on our website.”

South Carolina Amateur Radio Volunteers Ready

Although Isaias hasn’t turned into a monster hurricane, radio amateurs from all over South Carolina have been preparing for days as the South Carolina Emergency Operations Center geared up for the storm. Isaias was predicted to make landfall on the border of North Carolina and South Carolina.

“We have been in direct communication with our emergency support function (EFS-2) partners along with many other organizations to ensure our level of readiness is sufficient. Radio checks have been performed at SCEMD (South Carolina Emergency Management Division) and more conference calls among ARES leadership are planned,” said ARRL South Carolina Section Emergency Coordinator Billy Irwin, K9OH. Irwin said information about frequencies in use may be found in the Tactical Guide on the South Carolina ARES website.

 

 

MONDAY EDITION: BAND PLAN sell out by ARRL article. I notice the extra class gets shit. We were the ones that dragged our ass to the Custom House in Boston to be greeted by grumpy FCC employees and took a code test on an antique code tape machine and took a test that was actually hard and could not be memorized. I can live with the fact you can't get people to enter the hobby with the code requirement because they refuse to make the time and effort to learn the code and offer a no code tech light license that a 9 year old could pass....but why not give some extra stuff to Extra class hams that studied for for a real license?

Why hobby electronics is a great thing to take up

The Deccan Herald reports nothing is more satisfying than using a piece of electronic equipment built at home

The newspaper says:

Using a piece of equipment that you have built with your own hands is thrilling and I certainly was thrilled. An additional advantage is that you can save money through the do-it-yourself route. If you take a pair of loudspeakers, a DIY job will save you at least two-thirds of the cost for something that is similar sounding as compared to buying readymade stuff.

Whether it is for the thrill of building equipment, repairing gadgets or saving a bit of money, hobby electronics is very rewarding. Yes, it requires a bit of learning in the beginning but once the electronics bug bites you, it becomes an addiction.

Hi Jon...

Not being a close follower of the League, I didn't know that this was coming until I saw it on your site.  It makes me wonder why we bothered to study anything for a ham ticket.   Just think, we could have gone to a ham-in-a-day crash course, taken the test while it was all fresh in our little brains and been a ham.

I suppose the League is bleeding money like mad and thinks they might get a few members out of this.  If it's inevitable, I would like to see a provision that states that no Tech could have an amplfiier capable of more than 200 watts output on premises.  I'm betting that most of the new breed will bring their high-IMD leenyars down from 27 mhz and spew crap all over the bands.  Not that I expect that they'll honor the band limits anyhow...

Over a half century ago I went way up in the Customs House building, nervous as a whore in church, and got my ham ticket, as well as the First Class Commercial, which they ultimately turned into toilet paper as well.  Makes a fellow feel old...

The plan gives the no code technician joke license lots of digital privileges on the hf bands  including 20-40-75, next step will be a license and call sign included with the pricey ARRL membership. We are not alone in the dropping of requirements, police and fire departments have dropped physical requirements, swimming requirements, etc.....boot camp for the armed service is not what it used to be either, not complaining though, at least we still have young men and women willing to volunteer and serve rather than protest in the streets...

Hurricane Watch Net Activating as Hurricane Isaias Approaches US East Coast

The Hurricane Watch Net (HWN) activated on 14.325 MHz on July 31 at 1500 UTC as Hurricane Isaias [pronounced: ees-ah-EE-ahs] heads toward the US on an uncertain trajectory.  The Volusia County, Florida, and State emergency operations centers were reported at a Level 3 (Monitoring) status.

“For years I’ve said, ‘Just when you think you have Mother Nature figured out, she changes her mind,’” HWN Manager Bobby Graves, KB5HAV, said. “Shortly after Advisory 11 for then-Tropical Storm Isaias was issued [at 0300 UTC], an Air Force Reserve hurricane hunter aircraft found that the tropical storm had strengthened to a hurricane. The maximum winds had increased to 80 MPH with higher gusts making the storm a Category 1 hurricane.”

The National Hurricane Center (NHC) forecast for 0900 UTC called for Isaias to strengthen into a Category 2 hurricane during the next 24 hours.

“Unfortunately, Isaias appears to be taking a somewhat similar track along the US east coastline, such as Matthew in 2016 and Dorian in 2019,” Graves said. “Interests throughout the Bahamas, Florida, Georgia, South and North Carolina, and farther north need to keep a close watch on Isaias. This means the Hurricane Watch Net could be running another marathon activation.”

An NHC Advisory issued at 1500 UTC included a Hurricane Watch for portions of the Florida east coast from north of Deerfield Beach northward to the Volusia-Brevard County Line. A Tropical Storm Warning has been issued for portions of the Florida east coast from north of Ocean Reef northward to Sebastian Inlet and for Lake Okeechobee.

As of 1500 UTC, the NHC said the center of Hurricane Isaias was located near latitude 21.7 N, longitude 74.5 W, moving toward the northwest near 16 mph (26 km/h), and a general northwestward motion with some decrease in forward speed is expected for the day or so followed by a turn toward the north-northwest.  On the forecast track, the center of Isaias will continue to move near or over the Southeastern Bahamas today. Isaias is forecast to be near the Central Bahamas tonight, and move near or over the Northwestern Bahamas Saturday and near the east coast of the Florida peninsula Saturday afternoon through Sunday. 

“On the forecast track, the center of Isaias will continue to move near or over the Southeastern Bahamas today. Isaias is forecast to be near the central Bahamas tonight, and move near or over the northwestern Bahamas on Saturday and near the east coast of the Florida peninsula Saturday afternoon through Sunday.

“Tropical storm conditions are possible along portions of the Florida east coast beginning Saturday, and a tropical storm watch remains in effect. While storm surge watches are not currently needed for this area, they may be required later today, if the forecast track shifts closer to the coast. Heavy rains associated with Isaias may begin to affect south and east-central Florida beginning late Friday night, and the eastern Carolinas by early next week, potentially resulting in isolated flash and urban flooding, especially in low-lying and poorly drained areas. Isolated minor river flooding is possible in the Carolinas early next week,” the NHC said. “Hurricane conditions and dangerous storm surges are expected in portions of the Bahamas today and Saturday, and hurricane warnings are in effect for these areas. Preparations to protect life and property should be rushed to completion.”

The HWN seeks “observed ground-truth data from those in the affected area,” including wind velocity and gusting, wind direction, barometric pressure, and, if available, rainfall, damage, and storm surge. “Measured weather dat

First Digital DX contact!

The other day day I managed my first DX contact using a new mode, FT8.
It wasn't very far away, all of 2600 km or so, but it evoked memories of my first ever on-air DX contact nearly a decade ago. I should say thank you to YD3YOG for my 15m contact, fitting because my first ever was also on 15m as I recall. Unfortunately I never did log my first.

Recently a friend asked me how the two compared.

15m and logging aside, there's a lot of similarities, even though I'm a more experienced operator today when compared to when I made my first ever contact.

The preparation and the building anticipation is what made the contact all the sweeter.

A while ago I managed to connect the audio of my radio to a computer. This is pretty much the first step in starting to use digital modes. Essentially many common digital modes use an SSB transmission to generate and receive audio that in turn contains digitally encoded information.

There are hundreds of modes like this, from PSK31 to RTTY, WSPR, FT8, SSTV and many more. If you've not yet dabbled in this area, I'd recommend starting with WSJT-X. The software is so far the best tool I've found to make sure that your digital levels are correct and offers several popular modes to see how your station is operating. If you're asking for a first mode recommendation, I'd start with WSPR. Just do the receive part first, then work on from there.

There are many tutorials available, some better than others, so if the one you find doesn't float your boat, keep looking. A fly-over view is that there are several things that you need to get working and if they don't all work together, you'll get no result.

Obviously you'll need to install the software, but that's not the whole story. For the software to be able to control your radio, change bands, frequency and set-up things like split operation, you'll need to set-up the hardware to do this, in my case a CAT cable between the radio and the computer. You'll also need to set-up control software that knows how to talk to the hardware. In my case that's Hamlib on Linux, but it could be Hamlib or flrig on MacOS or something like OmniRig on your Windows machine.

The purpose is to control the radio. When you're troubleshooting, keep that in mind, hardware plus software need to work together to control the radio and this is before you actually do anything useful with the radio.

Then you need to have both hardware and software to have audio go between the computer and the radio. In my case the headphone and microphone connectors on my computer are connected to the data port on the back of the radio. If your computer doesn't have access to sockets you might need to use a USB sound-card. If your radio doesn't have an easily accessible port, you might need to have an interface.

The computer software in this case is likely setting the volume levels using the audio mixer in your operating system.

I will add that some radios have a USB socket on the back that combines both CAT control and audio. The principle though is the same. You need to make the CAT interface work, which is essentially a serial connection, and you need to make the audio work, which is essentially a sound-card.

Nothing else will make sense until you've managed to make those two work.

Then, and only then, can you try to launch something like WSJT-X, point it at the various things you've configured, then you can actually start decoding signals.

For WSJT-X to work properly, there's one more thing. An accurate clock is required. Likely you'll need to use a piece of software that knows how to synchronise with something called NTP or Network Time Protocol. The simplest is to point your clock tool at a time-server called pool.ntp.org which will get you global time coverage. Each operating system does this differently, but getting it right is essential before WSJT-X will actually make sense. You can visit time.is in a web browser to see how accurate your clock currently is.

So, get computer control of your radio working, get audio working, set the clock, then you can run WSPR, FT8, JT65 or any other mode.

I will note that I'm not attempting to give you specific computer support here, just an overview of what's needed before anything will work.

If you've been contesting then CAT control might already be operational. If you've been using a computer voice-keyer, then audio might also be ready. Depending on where you are on your digital journey, these steps might be complicated or trivial.

Once you've done all that you can start doing things like figuring out where satellites are or how to talk to the International Space Station, or use Fldigi to make a PSK31 contact or send a picture using SSTV or decode a weather fax.

When you've made that first digital DX contact, I'm sure that you too will have a sense of accomplishment!

THURSDAY EDITION: Nice vacation on a little lake in NH for a few days, ended up renting a week for next summer. Never turned a radio on in the truck or on the lake, made everyone happy!....Anyone looking for an Acom 1010 amplifier like new? I got one for you, doing a little upgrade here....NEW-CYCLE SUNSPOT ACTIVITY: Solar Cycle 25 is gaining strength. Today there are two new-cycle sunspots on the solar disk: AR2767 and AR2768. Both have magnetic polarities that identify them as members of Solar Cycle 25. Neither appears to pose a threat for strong solar flares, though, so the quiet of Solar Minimum continues.  ...

Traffic-Handling Webinar Launches Ham Radio Learning Series

A live presentation from ARRL North Texas Section Traffic Manager Aaron Hulett, K8AMH, inaugurated the new ARRL Learning Network on Tuesday, July 28. The webinar series features 30-minute presentations from experienced members covering a variety of amateur radio topics and interests. Hulett’s webinar, 'Relay Stations and the Art of Traffic Handling, 'introduced techniques and skills practiced by radio amateurs like himself who relay messages during emergencies, disasters, and other incidents that interrupt conventional telecommunications, including the internet. Through an overview of the ARRL National Traffic System, Hulett shared examples of preparing a radiogram and resources for finding traffic nets and other volunteers.

'Aaron hit a home a run,' said Bob Inderbitzen, NQ1R, ARRL Product Development Manager and moderator for Hulett's webinar. 'His presentation was the perfect balance of knowledge-sharing and enthusiasm that will surely motivate other members to try their hand at traffic handling.' A recording of the webinar is available for members to view

The webinars are hosted using GoToWebinar. Members are invited to ask questions during each webinar, and a 15-minute Q&A period follows each presentation for those who can participate longer. A running list of upcoming live presentations is available; and prospective attendees may register on the same page. ARRL members must first log into the ARRL website.

FCC Fines HobbyKing Nearly $3 Million for Marketing Unauthorized Drone Transmitters

The FCC has issued a Forfeiture Order  calling for HobbyKing to pay a fine of $2,861,128 for marketing drone transmitters that do not comply with FCC rules. An FCC Enforcement Bureau investigation stemmed in part from a 2017 ARRL complaint that HobbyKing was selling drone transmitters that operated on amateur and non-amateur frequencies, in some instances marketing them as amateur radio equipment. The fine affirms the monetary penalty sought in a June 2018 FCC Notice of Apparent Liability (NAL). The FCC said its investigation found that dozens of devices marketed by the company transmitted in unauthorized radio frequency bands and, in some cases, operated at excessive power levels. “Such unlawful transmissions could interfere with key government and public safety services, like aviation systems,” the FCC said.“We have fully considered HobbyKing’s response to the NAL, which does not contest any facts and includes only a variety of legal arguments, none of which we find persuasive,” the FCC said in the FO. “We therefore adopt the $2,861,128 forfeiture penalty proposed in the NAL.”

The FCC pointed out in the FO that it has previously made clear that “[d]evices used in the Amateur Radio Service do not require authorization prior to being imported into the United States, but devices for other services, including the CB service, require Commission approval.” The FCC investigation found that 65 models of devices marketed by HobbyKing should have had FCC certification.

Responding to the NAL, HobbyKing claimed to have ceased marketing the 65 models the FCC identified, but promised only to make “best efforts” not to market other noncompliant RF devices. “HobbyKing has a continuing obligation to market only radio frequency equipment that is properly authorized,” the FCC said. “We therefore remind HobbyKing that continuing to market noncompliant radio frequency devices could result in further significant forfeitures.”

HobbyKing has 30 days to pay the fine. If it fails to do so, the matter will be referred to the Department of Justice for collection.

AMSAT Partners with University of Maine WiSe-Net Lab to Develop State's First CubeSat

The University of Maine Wireless Sensing Laboratory (WiSe-Net Lab) and AMSAT have signed an agreement to collaborate on building and operating MESAT1, Maine’s first small satellite. Carrying an amateur radio payload in addition to science payloads, MESAT1 is set to launch sometime in the next 3 years under NASA’s CubeSat Launch Initiative (CSLI), which provides opportunities for nanosatellite science and technology payloads built by universities, schools, and nonprofits to ride-share on space launches. AMSAT President Clayton Coleman, W5PFG, celebrated the announcement.

“This is a great day for AMSAT and UMaine’s WiSe-Net Lab,” Coleman said. “This partnership is a true win-win for both education and the amateur radio community. The collaborative effort under AMSAT’s engineering and operations teams has once again succeeded to bring another opportunity to AMSAT.”

MESAT1 will be one of 18 small research satellites selected by NASA to carry auxiliary payloads into space between 2021 and 2023. The CubeSat is being developed in partnership with the University of Maine (UMaine) and the University of Southern Maine (USM), along with a trio of K – 12 schools. UMaine graduate students and USM undergraduates will collaborate on CubeSat design, development, integration, and testing.

UMaine’s WiSe-Net Lab, established in 2005, is involved in aerospace and space research. The lab was founded by Ali Abedi, KB1VJV, assistant vice president for research and director of the Center for Undergraduate Research at the university’s main campus in Orono. Lab researchers have developed the first wireless sensor network for NASA’s lunar habitation project and launched wireless leak detection to the International Space Station.

The MESAT1 initiative will enable K – 12 students and teachers in Maine to access space data for educational and research purposes and encourage students to pursue STEM (science, technology, engineering, and math) careers. MESAT1 was awarded $300,000 from NASA. The project also received $150,000 in NASA Maine Space Grant Consortium funding for graduate student research. Folding in additional funding from UMaine and USM to support undergraduate student research brings the total funding to $522,000 over 3 years.

AMSAT will provide a linear transponder module (LTM) along with integration and operational support for MESAT1. AMSAT’s LTM incorporates a VHF/UHF telemetry beacon, command receiver, and linear transponder. It will be available for worldwide amateur radio use once the satellite is commissioned. — Thanks to AMSAT and the University of Maine

Hurricane Watch Net Activates for Hurricane Hanna

The Hurricane Watch Net (HWN) has activated for Hurricane Hanna, the first hurricane of the Atlantic Hurricane season. The storm is poised to make landfall along the Gulf of Mexico. A Category 1 storm, Hanna has maximum sustained winds of 75 MPH. As of 1200 UTC, the storm was about 90 miles east-northeast of Port Mansfield, Texas, and about 100 miles east-southeast of Corpus Christi, Texas.

“The year 2020 has been a strange year in every way, and the weather is no different,” HWN Manager Bobby Graves, KB5HAV, said. “Just a few hours ago, it looked as though we would be activating for Hurricane Gonzalo. Well, that storm had other ideas. The same can be said for what had been Tropical Storm Hanna in the Gulf of Mexico. All along, it looked as though this storm would make landfall as a Tropical Storm.”

Graves said the net activated today at 1130 UTC on 14.325 MHz — its primary net frequency. “If conditions require, and they most likely will, we will operate simultaneously on 14.325.00 MHz and 7.268.00 MHz,” Graves said. The HWN will remain active until 2200 UTC, “or until no longer required by the National Hurricane Center.”

Via its amateur radio volunteer members, the HWN gathers observed ground-truth weather data from those in the affected area. “We are also available to provide back-up communication to official agencies such as emergency operations centers, Red Cross officials, and storm shelters in the affected area,” Graves added. “We will also be interested to collect and report significant damage assessment and storm surge data back to the forecasters as well as FEMA officials stationed in the National Hurricane Center.”

WX4NHC at the NHC also has activated for Hanna, and will participate in the HWN on 14.325 MHz, as well as on the VoIP Weather Net, WX-TALK Conference node 7203 / IRLP node 9219). Contact WX4NHC via Winlink (subject must contain “//WL2K”) or complete a WX4NHC online Hurricane Report Form.

Due to COVID-19 precautions, WX4NHC operators are operating from their homes.

Foundations of Amateur

What do you talk about?

When was the last time you told anyone anything about your hobby? What about someone who isn't also an amateur?

Have you ever considered why there is a perception that our hobby is dying, why it"s running out of people, why we struggle to get air-time in mainstream media, why attracting new members is hard and why there is a very narrow range of understanding about what our hobby is, what it does and how it's relevant in the world today?

I"m a radio amateur. So are you. You might not be licensed yet, but the fact that you're here right now indicates a willingness to understand and learn, to participate and question.

Those qualities are the fundamental building blocks that make up a radio amateur.

I"m also a self-employed computer consultant, a radio broadcaster, an interviewer, a software developer, a public speaker, a blogger, author, publisher and a partner. My friends include people who are process managers, astronomers, gynaecologists, mariners, tow truck drivers, communications technicians, volunteer fire-fighters, business owners, employees, retirees, fathers, mothers, old, young and everything in between. Radio Amateurs one and all.

When you sign up to be an amateur, you don't give up all the other things you are. You don"t stop being a member of society, you just add in another box marked radio amateur and you get on with your life.

If you get into this hobby you begin to realise that it sneaks into everyday life all the time. You use it to figure out how something works, or explain why it doesn't, you use it to trace a circuit or to plug in your new surround sound system. You use it to encourage curiosity in your children and to talk to your grand-children. It's not an add-on, it's part of who you are.

That's always been the case, but the perception in the general public has not been like that, it's been based around the idea that being a radio amateur is being special, being separate, being knowledgeable, studied, licensed. The reality is that the world we live in is more connected than ever and the things we once did in isolation are now part of mainstream life.

There is a perception that amateur radio is dying. Articles describe how we need to attract more people, how we need to appeal to children, how we need to recruit, become sexy or relevant. There's discussion about what's broken in the hobby, how we need to fix it.

I think that none of those things are what's in need of investigation. I think it's us. You and I. I think we need to stop being shy about being a radio amateur, about what we do and why we enjoy it; what it means and how it works.

When you talk about your activities of the day, if you made a rare contact with Tuvalu, or managed to connect your computer to your radio, or made an antenna work, or climbed on a hill or learnt Morse Code, you need to share your victories and the excitement that they bring you.

As a society we're not shy about tweeting what we had for breakfast, sharing an interesting picture or discussing an article we saw on reddit. Fundamentally what you do and who you are is worth talking about and sharing.

So, next time you talk about going camping, or discuss a barbecue you had with friends, or relate to your friends something that happened, don't be shy about your amateur radio affiliation.

It's not a secret society, it's not weird or embarrassing, it's just part of what makes you who you are.

High School Marine Buoy Transmitter Now Active on 20-Meter WSPR

Phil Karn, KA9Q; Randy Standke, KQ6RS, and members of the Mount Carmel High School Amateur Radio Club (MCHSARC) in San Diego have constructed and deployed an amateur radio marine buoy in the Pacific. The buoy, which transmits WSPR on 14.0956 MHz USB, has already been heard around the continental US, Brazil, Hawaii, Japan, Costa Rica, Australia, and South Africa.

“Over the past year, Randy and I have mentored the MCHSARC in designing and constructing a simple marine buoy that was deployed from the RV Sally Ride [on July 16], about 700 kilometers off the coast of southern California,” Karn said in a post on the AMSAT Bulletin Board. “It is up and transmitting WSPR on 20 meters using the call sign KQ6RS, and is being received all over the US and into Canada and Brazil.” Karn is blogging about the project with updates.

The electronics are the 20-meter WSPR version of the WB8ELK “pico tracker” that has been flown on long-duration balloons. “We removed the solar panels and substituted 21 ordinary alkaline D cells, wired to supply 4.5 V,” Karn explained. “We estimate battery lifetime will be 6 months.”

Karn said that the project made use of everyday hardware. The buoy — essentially a spar buoy — was constructed using a 5-foot section of 4-inch PVC pipe, with sufficient ballast in one end of the pipe to permit it to float vertically in the water. The top is closed using a sewer pressure test plug, which has a bolt in the center that acts as a convenient feed-through and antenna mounting point. The antenna is a stainless-steel CB whip with a matching network.

“We use the sea as a counterpoise, but to avoid direct metal/sea water contact, we lined the inside of the pipe with copper tape to form a capacitive connection,” Karn said.

During initial flotation testing, the project team found that the ballasted pipe alone was remarkably stable in pitch, roll, sway, and surge, but oscillated a lot in heave — i.e., up and down movement. Cross arms were at the water line to add drag in the vertical direction, to counter the issue.

“It wasn’t our intent to mimic a religious icon, but that’s where the physics went,” Karn said. Because sea water was required to tune the antenna, Standke floated the buoy off a dock in Mission Bay.

“We tried to make this thing as rugged as we could,” Karn recounted, offering his favorite saying to the students: “The sea always wins in the end, but we can delay that long enough to be useful.”

Deployment was to be from a NOAA vessel in April, but the trip was canceled due to the COVID-19 pandemic. Standke secured a trip on the RV Sally Ride, a research vessel operated by Scripps Institute of Oceanography.

The first reception report was on July 16 at 12:52:30 UTC from grid square CL89eu, although the current carried the buoy east into CL89fu at 20:32:30 UTC. The buoy (KQ6RS-1) can be tracked on the APRS and WSPRnet sites.

Karn said the project team is already planning its second buoy, which may include two-way links, satellite tracking, and sensors. 

Chris Brault, KD8YVJ, is 2020 Amateur Radio Newsline Young Ham of the Year

Christopher “Chris” Brault, KD8YVJ, of Liberty Township, Ohio, has been selected as the 2020 Bill Pasternak WA6ITF Memorial Amateur Radio Newsline Young Ham of the Year (YHOTY). The son of Jocelyn, KD8VRX, and Kimberly Brault, Chris, 18, was the recipient of the 2015 ARRL Hiram Percy Maxim Award. A ham since 2014, he credits his father for being his guide into amateur radio, recalling watching and listening to his dad operating mobile.

“We would be on a road trip somewhere,” Chris said. “We’d be talking to people along the way, it seemed like fun.” Chris is a member of the Dayton Amateur Radio Association, the West Chester Amateur Radio Association, and the Ohio Valley Experimenters Club.

A senior and honor student at Saint Xavier High School in Cincinnati, Chris helped restart the school’s amateur radio club, W8GYH. He has also been recognized as the 2017 ARRL Great Lakes Division Young Amateur of the Year, and he took part in the 2017 Dave Kalter Youth DX Adventure to Costa Rica with other up-and-coming young radio amateurs. In 2017, he was a Youth Forum presenter at Dayton Hamvention® and HamCation in Orlando.

Chris serves as social media director for the Youth on the Airorganization and is a contesting mentor for young hams involved in its programs. He is a tour guide for the National Voice of America Museum of Broadcasting in West Chester, Ohio, and assists in mentoring young operators at its ham station, WC8VOA. He participates with his dad in Scouting’s Jamboree on the Air (JOTA) each October.

The YHOTY award is traditionally presented during the Huntsville Hamfest in August, but the event was canceled this year because of the COVID-19 pandemic. The Young Ham of the Year Award was established in 1986 by Newsline editor Bill Pasternak, WA6ITF, who died in 2015. — Thanks to CQ Communications

Dumb Questions about Dummy Loads & SWR Meters

By Martin Brossman - KI4CFS

People said I was a Ham all my life and in fall 2003 I became one. Loving the hobby I wanted to really learn how things work and especially how to test and trouble shoot my own problems. I read in 4 books the importance of an SWR Meter and a Dummy load but the paragraph stopped their. It looked like they cut and pasted the paragraph about these two devices from one book to the next. So I started searching the web for answers on just how do you use SWR Meters & Dummy loads. I found out how you can build them, the problems with low price ones, which models were used to test which equipment but very little on how to really use them. I was clear I was not going to spend $1100.00 on a meter but when I asked which were good ones they referenced the real expensive ones. So I explored the wisdom of Ham's on eham.net in required to using SWR Meters & Dummy loads that were under $200.00 and here is what I learned. I found this very useful and wanted to thank all the ham's that contributed. You will see some redundancy in this article and that is because I am offering different Ham's perspective on the same topic. Sometimes I need to read something in a slightly different way to understand it. May you find these questions and answers helpful to you also!

Question: What is an SWR meter & a Dummy Load AND how do they work?

KA5N: The primary use of an SWR meter is to determine the amount of reflected power in an antenna system. The accuracy of inexpensive meters is relatively unimportant and 10% is good enough. Whether the SWR is 1.1: or 1.3:1 isn't critical. The SWR number accuracy is determined by how closely matched the measurements of the forward reading and the reverse reading are. So in any SWR meter the SWR readings should be pretty close. Where accuracy enters the picture is the forward power indicated. If the meter reads 100 watts is the actual power 90 watts, 100 watts, or 110 watts? For all practical purposes 10% accuracy is good enough. Even the best SWR meters are only about 5%.

A dummy load is used to check the operation of a transmitter and also can be used to check the SWR meter. A good dummy load should show an SWR of about 1.1:1 over its operating range. If your SWR meter suddenly shows an SWR of 5:1 on the dummy load there is a good chance either the meter or the dummy load have gone bad. If your antenna SWR suddenly changes drastically then you check with the dummy load and if that reading is ok something has gone wrong with the antenna system.

Tuning an antenna with a SWR meter is easy with an antenna tuner. You simply tune for lowest SWR (lowest reflected power). Tuning an antenna where you are making an installation means to adjust the length (or coil tap, or capacitor) to give low SWR over the range you intend to operate.

An SWR meter is not a laboratory instrument and for amateur use 10% accuracy is good enough. Using the meter requires a lot of reading of the ARRL Handbook and Antenna Book (and other information sources) and a good deal of hands on use. Learning to diagnose problems in antenna systems from SWR readings requires a good understanding of antenna principles and logical troubleshooting.

K0RFD: How does an SWR meter work? Depends on the meter. There's a pretty good explanation of one type of very simple circuit here:

http://engphys.mcmaster.ca/~elmer101/rfpower/swrtheory.html

How does a dummy load work? It's just a big dumb resistor, non-inductive so that the load is 100% resistive. Essentially, it works by converting nearly all of the transmitter's power to heat instead of radiating it as electromagnetic radiation.

N7DM Another interesting thing about Dummy Loads. Often you will hear or read of someone working across the State or Town...from a Dummy Load, or in one QST article, a Light Bulb. I wouldn't bet YOUR life on it, but I am pretty much sure that the actual radiation was not from the Dummy itself, but from the shield of the COAX feeding it. I have run tests...receive only of course...feeding my old Heathkit Dummy with both coax and twinlead. With twinlead, no length will let me hear a thing. With coax, I CAN hear... and the longer the coax run, the better. So I am pretty sure it goes back to the old Unbalanced Feed to a Balanced Load 'thing'..

Question: How do you use SWR meters with a 10% error, accurately?

K5LXP: Well, if it's specified as 10% accuracy, you'll never have more than a 10% confidence in the reading. However, rarely do you need to know the exact SWR value. Most of the time you're only interested in finding the minimum value (say, when adjusting a tuner), in which case even very inexpensive SWR meters will do this very well.

K0RFD: How do you use a 10% meter accurately? You don't really need to. 10% isn't enough change in reflected power to worry about in most cases. Most meters detect the zero or near-zero reflected power condition pretty well. That's really what you care about. With a cross-needle meter, I generally don't try to read the actual SWR. I just tune for minimum reflected power.

W4TYU: A meter's accuracy is usually expressed as a percentage of full scale reading (5% FS). This means that the error of any reading will be that ammount in error. e.g. If full scale is 100 and the error is 5%FS then the actual error is 5 units at any reading on the meter. If the reading is 50 the actual error would be +/- 5.

Also,remember that that there is a difference between accuracy and precision. A reading can be precise but not accurate.

Question: How do you use an SWR meter to tune an antenna

K5LXP: In the case of a dipole, you would check the SWR of the antenna under test at fixed intervals (say, 25kHz) across the band it was cut for, and graph the measured SWR vs frequency. The point where SWR is minimum is considered the resonant point. Once this point is known, the length of the antenna can be adjusted to move the resonant point to the desired frequency.

K0RFD: How do you use it to tune an antenna? well, ideally you want to tune the antenna so that the minimum SWR is at or near the part of the band where you operate. Measure the SWR at several frequencies within the band. If you want to move the minimum SWR higher in frequency, make the antenna a bit shorter. If you want to move it down in frequency, make the antenna a little longer. This assumes that the minimum SWR occurs in a range where you are allowed to transmit. Often when you build a new antenna, it's pretty out of whack and the resonant frequency will be outside the range where you are allowed to transmit. (DO NOT TRANSMIT OUT OF BAND) In that case, you measure the SWR at each end of the band. If the SWR is lowest at the lowest frequency of the band, chances are your antenna is too long, make the antenna a bit shorter and see if the minimum swr is within the band. If the lowest SWR is at the high frequency end of the band, then make the antenna a bit longer, again hoping you can get the true minimum inside the range where you can transmit. This is just a rule-of-thumb -- sometimes you can't really tell. In that case, borrow an Antenna Analyzer or Receiver Noise Bridge from somebody and find where the resonant frequency REALLY is.

Question: What is a dummy load used for?

K0RFD: Well the "classic" use was to tune the tank circuit of a transmitter or amp with tube finals without going on the air and QRMing everybody. But a dummy load is useful whenever you want to test or adjust something into a known impedance without going on the air.

Question: How do you use the SWR Meter with a dummy load?

K5LXP: Using an SWR meter with a dummy load is a good way to test cables. Obviously, a dummy load will always present a 1:1 match so you won't be testing it's SWR. But if you *do* measure a mismatch while using a dummy load, the cable or connectors are suspect.

N8UZE: Dummy loads can be used for several purposes. One of these is to tune the old tube type radios so that their output impedance is 50 ohms. On the moder non-tube radios, this is not needed. Another use of the dummy load that does apply to modern radios is adjusting the mike gain. Instead of doing this on the air, you can do it transmitting into the dummy load.

Question: How do you use the SWR Meter / Dummy Load, to determine if your feed line is good or bad?

K5LXP: Using a short patch cable, transmit into the dummy load and set the forward reading for full scale. Insert the cable under test and see that the needle still deflects the needle to almost full scale. If it's significantly lower, there's a problem. If there's any reflected power at all, there's definitely a problem. If the SWR meter has a wattage scale on the forward reading, you can see just how much attenuation the cable has at the frequency you're testing at.

K0RFD: How do you use it to determine if the feedline is good or bad? Connect the dummy load directly to the meter and measure the SWR. It should (ideally) be 1:1 or close. Then connect the feedline to the meter and connect the dummy load to the other end. If the SWR is very high, then chances are the feedline, one of the connectors, or (most commonly) one of the solder joints in the connector is bad. Basically, you are just taking the antenna out of the equation and measuring the SWR of a known impedance with and without the feedline in the system.

Question: How can you determine if the SWR meter is accurate "enough"?

K5LXP: You can connect some known mismatches to the antenna port and see what the readings are. Of course, a 50 ohm load will read 1:1. A 25 or 100 ohm resitive load will read 2:1, and a 12.5 or 200 ohm resistive load will present a 4:1 SWR. No load at all, or a direct short should read infinity to one. Usually, especially with inexpensive meters, the accuracy goes down as the SWR goes up. Pretty much any meter will tell you 1:1, beyond about 5 or 6 to one is tough to accurately measure with a simple instrument.

K0RFD: How can you tell if a meter is accurate "enough" without expensive test equipment? Depends on what you mean by "enough". I really don't pay much attention to absolute SWR values so long as my antenna is close enough to avoid going into power foldback, which most solid-state transceivers do at pretty low SWRs. I just use my meter to find the SWR minimum when I am tuning a new antenna, and to see if anything has changed drastically from last time. The absolute accuracy isn't important, and the precision is usually good enough to tell me if my antenna fell down or the coax came unhooked in the last windstorm.

Question: How can you determine if the 20W range is accurate compared to the 200W range?

K5LXP: Simply sending the same forward power into a dummy load should result in the same readings between the scales, albiet with a bit less resolution on the higher scale. For instance you could set your transmitter for a full scale 20W forward power, then switch to the 200W range. It should still read 20W. The actual power may or may not be exactly 20 watts depending on the accuracy of the meter's calibration. Verifying the actual accuracy is going to require some known standards and an accurate means of measuring voltage or current, or a known calibrated wattmeter?

Question: How do SWR meters tend to go bad, how would you know it, if it did?

K5LXP: A second one is handy to have to compare readings against and is inexpensive. The dummy load and known mismatch standards are a good means of finding a bad meter. The way most VSWR meters work it's not often they suddenly give inaccurate readings. If anything, they will fail completely in one direction or the other due to bad diodes.

K0RFD: SWR meters can go bad in a lot of ways. If it's a D'Arsonval meter, the movement can go bad. You can put too much power into it and burn it out. Connectors can go bad, solder joints can go bad, just about the same things that can go bad with any other piece of electronics. How do you tell? Well, if you can't get a reading on the "calibrate" setting, or if nothing moves under any circumstances, or if you get readings that make no sense at all, test with a dummy load, or borrow a known good meter from somebody else and compare.

Question: How do you use and SWR Meter, what are the different ways?

K5LXP: The most common application is to indicate a good match between a transmitter and feedline. Testing coax is probably the second most. If I need to know any more about a tuned network, antenna, or matching section I'll usually resort to my MFJ-259 analyzer that will tell me inductance, capacitance and a few other parameters that SWR meters cannot indicate. Perhaps some of the real older timers here can pass on some measurement tricks that can be done with basic VSWR meters. One that I know if is how to use an inexpensive 'CB' SWR meter on VHF. One connects it in the usual fashion between the transmitter and the load, and you set the meter full scale per usual. But instead of throwing the switch to reflected to get the SWR, you disconnect the cables on the meter and reverse the connections, and now the forward reading becomes the reflected reading. What this does is use the same diode for both forward and reflected, eliminating the error incurred by the second reflected power diode, which for an inexpensive meter won't be a well-matched pair.

Question: What is the relationship between SWR and Field Strength (radiating energy)?

N7DM: There is no direct relationship between SWR and Field Strength. Field strength basically is a direct function of the amount of current flowing in an antenna. WHERE that field is 'encouraged' to go is dependant on other things...height, ground conductivity, obstructions, other driven elements or parastic elements...etc.

SWR is simply 'ONE' way of numerically stating how well 'something' is matched to something else. There is an SWR on your feedline, IF your antenna feedpoint impedance is not EXACTLY the characteristic impedance of your feedline. There is another SWR on the tiny little piece of coax in your rig that goes from the output filter to the Antenna Output connector, IF the input to your feedline is not EXACTLY what your rig's output impedance is...50 ohms? The only way either of these SWR's can effect your 'Field Strength' is if either one of them permits losses so that some of your output power [causing current in the antenna to flow]...is lost before it gets to the antenna.

KI4CFS: SWR does NOT tell you how much radiating energy is coming from your antenna.
SWR is relevant only when transmitting, for the most part. It represents the amount of power coming back into the radio. You of course do not want a lot coming into the radio for you do not have an efficient transfer of energy AND you may be putting a strain on the 'finals' (components in the radio) of your radio, also may increase RF in the Ham Shack. BUT low SWR does not mean you are transmitting a strong signal. For example a Dummy Load almost transmits nothing for it is converting all the electrical energy into heat showing a 1:1 or Low SWR. Without something that is testing the actual radiating energy from the antenna and how it changes with changes in SWR you are not getting a total picture.

Question: What is the difference between the Peak Envelope Power (PNP) and Average Power?

N8UZE: The study guide "Now You're Talking" has a fairly thorough explanation. When you were originally studying, there was so much to learn that this probably didn't sink in. Go back and reread it now. However basically as you talk into a microphone on sideband, the amount of power output will vary as you talk. Most meters will give you an Average Power reading. The reading on this type of meter will be and should be less than the max capability of your radio. If it reads full power then you are overdriving the radio and splattering all over the band. If you have a meter that reads Peak Envelope Power instead, it will jump up to max at the points where your voice is max. On FM, AM, and CW both types of meters will give the same reading as it will read the carrier for these modes.

Question: Are their other test tools worth having or having access to (barrowing)?

KI4CFS: From ham's I talked to on the radio the other test tools that seem worth having are a volt-ohm meter, an antenna analyzer, a field strength meter, and a frequency counter. An antenna analyzer hooks directly to the antenna and lets you know information about your antenna with out having to use or endanger your radio. The field strength meter lets you know that RF is radiating out of your antenna and the relative strength of it. The frequency counter tells you the frequency that is dominate in its environment (which would be YOUR antenna if it was radiating well). Last the volt-ohm meter is used to measure AC & DC voltage and DC resistance.

I want to thank all the good natured ham's that have contributed to this resource. My intention is that others find this useful as well. This is a wonderful hobby where both mentoring and community support are richly alive! I truly feel more knowledgeable with my SWR meter from the comments I received and have used them more.

Webinar Series

ARRL is launching a new webinar series to help introduce more members to the variety of activities and opportunities that radio amateurs enjoy. The ARRL Learning Network will offer live presentations by member-volunteers, for members. Like hamfest forums and radio club presentations, the webinars are intended to help participants get more active, involved, and engaged in amateur radio.

Presentations are 30 minutes each, making them easy to fit into a lunch break or as a short evening activity. A 15-minute question-and-answer period follows each presentation for those who can participate longer. The webinars will be hosted initially using GotoWebinar. Webinars will be recorded, and some presentations will be available for future viewing by members and ARRL-affiliated radio clubs as part of an ARRL Learning Network library.

A running list of upcoming live presentations is available. The web page is the place to register to attend each webinar and requires members to log onto the ARRL website.

Unauthorized Transmissions Reported in 144 MHz Satellite Allocation

The Deutscher Amateur Radio Club (DARC) reported unauthorized transmissions in the 144 MHz satellite segment of the 2-meter amateur radio primary allocation. DARC said that signals from illegal transmitters in the 144.010 to 144.020 MHz range are coming from “water vitalizers” or “water energizers.” The manufacturer specifies 144.015 MHz as the transmit frequency in its product description. The DARC Electromagnetic Compatibility (EMC) Department seeks further details and location information in preparation to file a complaint.

“The devices apparently generate fields with considerable field strength and a long range,” DARC said. “The signals appear increasingly in the morning or in the evening.

The illegal transmitters are typically in operation from 5 to 60 minutes (in multiples of 5 minutes). The signal is generally very stable in frequency, but occasionally shows short-term fluctuations of up to a few hundred hertz.” The carrier is not modulated.

The 144.000 – 146.000 MHz band is allocated globally to the Amateur Radio and Amateur Satellite Services on a primary basis, and is the only globally harmonized amateur radio VHF band. DARC has posted a video of the unauthorized transmission.

Radio Amateurs Help Air Ambulance

Perus Radio Club Peruano (RCP) reports that Guillermo Guerra, OA4DTU/XQ3SA, and the Peruvian Relief Net assisted an air ambulance en route to Easter Island on July 9 after its satellite communication equipment failed. The aircraft was about 1,000 nautical miles from the continent, so the pilot tuned to the Peruvian Relief Net on 7100 kHz.

Net control station OA4DTU and Giancarlo Passalacqua, OA4DSN, were still on frequency, and communication was established with the aircraft. The pilot detailed its tenuous connection and requested support to communicate via telephone with Ocean Air Control, a service of the Directorate General of Aeronautics of Chile, which watches over 32 million square kilometers of air space off the Chilean coast in the Pacific.

Authorities were already on alert for the aircraft because of the communication loss, plus the HF at the Easter Island tower was inoperative. About 10 phone calls were made to point out the aircraft’s position and route schedule, as well as any additional information needed. Other hams in Peru were listening in and standing by.

Guerra remained in contact with the aircraft until he was sure that it would reach its destination. At approximately 2330 UTC, the pilot reported making VHF contact with the Easter Island control tower for landing instructions. — Thanks to Radio Club Peruano

Chain Home Radar - Battle of Britain Anniversary

August sees two GB80 Special Event Stations come on air marking the critical role that radar played in the Battle of Britain 80 years ago

In mid-August 1940 as events unfolded, the radar stations such as Ventor on the Isle of Wight bore the brunt of the initial wave, but stayed on air to play a vital role. Unlike its modern counterparts, the pioneering Chain Home Radar system operated over HF to VHF (~20-55 MHz).

GB80CH (Chain Home) will be operated from Chelmsford in Essex, which has the most complete surviving radar tower from the Battle of Britain. Originally located at Canewdon near the Essex coast, the 360ft tall Chain Home mast was moved to what was Marconi Research Centre in the 1950s (now BAE Systems) in Great Baddow, where it has recently been given listed status. In recent times, it has supported amateur experiments on 160m and 472kHz. The BAE Systems Great Baddow Amateur Radio Club, with amateur colleagues in local clubs, will be operating across the HF+6m bands.

GB80BRS will be operated to commemorate Bawdsey Radar Station in Suffolk, which was where radar was developed in the late 1930s and was the location of the world’s first operational radar station. This will be the latest SES following several previous commemorations including in 2015 when the 80th anniversary of the first demonstration of working radar was made in the UK.  Operation will be on 10m to 80m bands, SSB, CW and FT8.

Electronic QSL only.

Watch The Resurgence Of Amateur Radio - A Silver Lining Of COVID-19

Today’s Global Maritime Distress and Safety System (GMDSS) regulations requires that every ship carry old-school HF radiotelephone and radiotelex equipment but, traditional radio is rarely used aboard ship. The problem is twofold. Today’s satellites are more convenient and reliable than HF radio and most land based radio stations have closed or operated on reduced availability.

During times of peace and prosperity, the death of traditional radio isn’t a problem on anyone’s radar but, COVID-19 has reminded us that we need to be prepared for the unexpected, especially considering the fact that modern systems like satellite radio are vulnerable to cybersecurity threats. The good news is that HAM radio has seen a resurgence during the past few months. Around the world, thousands of new amateur radio operators have used their time in quarantine to study for a radio license and many standby on HF stations like 14.300 MhZ to provide free information and services to ships.

Recently the popular YouTube channel Ham Radio Crash Course (HRCC) invited gCaptain to discuss the use of radio at sea. In this episode gCaptain founder and HAM radio operator K5HIP, John Konrad, discusses amateur radio use aboard ships including how gCaptain used radio to break a major news story

If you are interested in helping maintain this critical link we encourage you to subscribe to HRCC’s youtube channel, apply for an amateur radio license, discuss the topic on gCaptain’s forum, and, most importantly, start using your HF radio at sea to connect with maritime radio nets like 14.300. The more we learn about and use these free services, the more likely they will be available during the next global crisis.

Tokyo Ham Fair cancelled ...shucks..

The JARL has announced the largest amateur radio event in the world, the Tokyo Ham Fair, due to to held Oct 31 - Nov 1 has been cancelled due to Coronavirus

The Tokyo Ham Fair was first held in 1977 at Harumi Fairgrounds which was located in Harumi, Tokyo, and has been held annually ever since. In 1996, the venue was changed to Tokyo Big Sight, which is located in Ariake, Tokyo. From 1999 to 2001, the venue was Pacifico Yokohama, located in Yokohama, Kanagawa prefecture with the event returning to the Tokyo Big Sight in 2002.

In 2019, 42,000 people are reported to have visited the event which usually takes place in August. For 2020 it was planned for Oct 31-Nov 1 because of the expected Olympic and Paralympic Games during the summer.

A translation of the JARL announcement reads:

A meeting was held on July 16 to discuss whether or not to hold the "Amateur Radio Festival Ham Fair 2020", in light of the Coronavirus outbreak.

Even if measures were taken to ensure safety in accordance with the Government and Tokyo's infection prevention measures and the "Guidelines for Preventing New CoronaVirus Infection at Exhibitions, etc." published by the Tokyo Big Sight, it was difficult for visitors and exhibitors to prevent and ensure the safety of new coronavirus infections, and it was concluded that the Ham Fair should be canceled.

We are very sorry to announce that we have decided to cancel the Ham Fair 2020.

The timing of the next fiscal year will be postponed due to the postponement of the Olympic and Paralympic Games, but we will inform you as soon as the schedule and venue are decided.

Thank you for your continued cooperation.

WWII RAF veteran GW3EJR celebrates 100th birthday

The Tivyside Advertiser reports John Armstrong GW3EJR celebrated his 100th birthday on Saturday, July 18, 2020

A Cumbrian by birth, John spent his childhood growing up in the idyllic setting on the edge of Lake Ullswater, with his parents, an older sister and a younger sister.

From the age of five he would walk the one-and-a-half miles to school wearing clogs on his feet. They lived a simple country life with John’s father growing a very productive vegetable garden and they kept chickens which meant they were fairly self-sufficient, and often ate rabbit and game they had caught.

John has had an amateur radio licence since 1948. He taught himself the Spanish language which he perfected over time when talking to his many friends in Spain and ‘over the air’.

Nature Communications Article Features LO-94, First Lunar-Orbiting Ham Radio Spacecraft.

Nature Communications Article Features LO-94, First Lunar-Orbiting Ham Radio Spacecraft A July 9 Nature Communications article, “Design and flight results of the VHF/UHF communication system of Longjiang lunar microsatellites,” describes the Longjiang-2/Lunar-OSCAR 94 (LO-94) spacecraft, which carried the first amateur radio communication system into lunar orbit.

As a part of China’s Chang’e-4 lunar far side mission, two lunar microsatellites for low-frequency radio astronomy, amateur radio, and education — Longjiang-1 and Longjiang-2, were launched as secondary payloads on May 20, 2018, along with the Queqiao L2 relay satellite. Five days later, Longjiang-2 successfully inserted itself into an elliptical lunar orbit of 357 × 13,704 kilometers (221 × 8,496 miles) to become the smallest spacecraft to enter lunar orbit with its own propulsion system. The satellite carried a VHF/UHF SDR, designed for operation with small ground stations.

The article describes and evaluates the design of the VHF/UHF radio and the modes used. Flight results of the VHF/UHF radio are also presented, including operation of the radio, performance analysis of downlink signals, and the first lunar orbit UHF very-long-baseline interferometry (VLBI) experiment.
